An information system (IS) refers to a collection of multiple pieces of equipment involved in the dissemination of information. Hardware, software, computer system connections and information, information system users, and the system’s housing are all part of an IS.
There are several types of information systems, including the following common types:
Operations support systems, including transaction processing systems
Management information systems
Decision support systems
Executive information systems
An information system commonly refers to a basic computer system but may also describe a telephone switching or environmental controlling system. The IS involves resources for shared or processed information, as well as the people who manage the system. People are considered part of the system because without them, systems would not operate correctly.
In short, We build Information System, whether they are used by organizational business units like, Customer Care, Human Resources, Sales and Marketing, Finance and Accounting, etc.
If you dont understand Information System then some people may call you a techno-jockey.
